abf convergence problems

Hi all,

I have been using the ABF methods in order to estimate some energy around a
phi-angle in a peptide with 8 residues. I have applied the following

fullSamples 5000
dSmooth 0.1
forceConst 1.0

I have been running the simulation for 12 ns and the distribution is not
uniform and some of the gradients are around -0.15. Is there a way to speed
up convergence - any comments or suggestions appreciated.

Thanks in advance
